Objective: This study aimed to investigate Pre-service early childhood teachers' perceptions and roles regarding young children's free play time. Methods: The study utilized the photovoice method and involved 21 pre-service early childhood teachers who expressed interest in participating. Participants were enrolled in an infants teaching methodology class in B city. The study involved four virtual meetings conducted via untact teams, and the automatic recordings of these meetings were transcribed for analysis. Results: The results revealed that pre-service early childhood teachers recognized young children's free play time as a period to enjoy full freedom, develop as the main agent of their lives, and express their imagination. Furthermore, pre-service early childhood teachers perceived their roles during young children's free play time as a specialist infant observer, a connector between play and learning, and a versatile supporter. Conclusion/Implications: The findings suggest the need for a systematic curriculum to provide pre-service early childhood teachers with a balanced perspective and awareness of the meaning of free play and teacher roles. The study highlights the importance of expanding pre-practice courses for observation of play and field-oriented curriculum for incumbent teachers.

The purpose of this study is to investigate the change of mathematics pre-service teachers' teaching behaviors in microteaching. This study is organized along the following lines: 1) mathematics pre-service teachers conduct twice microteachings, 2) the microteaching recordings and lesson observation reports written by pre-service teachers are analyzed. Through reviewing the first microteaching, pre-service teacher have reviewed and found out improvements of their teaching. In the second microteaching, pre-service teachers' teaching behaviors have been positively and effectively changed with respect to teaching methods, proposal of learning objectives, prior knowledge usage, presenting lesson's content, concise descriptions, brief language usages, multimedia, and appropriate questions. However, they frequently used inappropriate expressions from their unconscious habits. Therefore, the educational institutions should provide opportunities involved in well-structured microteaching training program with pre-service teachers, which in turn, help pre-service teachers to have more positive teaching competence.

The purpose of this study was to provide fundamental data and implication for forming desirable viewpoint of mathematics lesson critique and for improvement of expertise in lesson by compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers. For the achievement of the purpose, The lesson critique materials of each 25 pre-service and in-service mathematics teachers were collected and arranged, and compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers by using the standard for analyzing viewpoint of lesson critique composed of two categories, five main codes and 18 sub codes. The results of this study, both pre-service and in-service teachers have tendency for criticising lesson focusing on the practice rather than plan of lesson and both pre-service and in-service teachers showed evaluative reaction in most of critical statements and used positive ones rather than negative ones. The only pre-service teachers, though minor of them, showed non-evaluative reaction in criticising class and most of the statements were just description and explanation without any their own judgement for the scenes and activities of lessons and most of pre-service teachers have tendency to include reflection and introspection for their own class in lesson critique.

최근의 건설사업에서는 전체 건설공사 수행과정 중 특히 Pre-con 단계의 중요성이 점차 커지고 있으며 Project 성패에도 큰 영향을 미치고 있다. 그러나 현재 우리나라 건설사업은 Pre-con 단계에 대한 정확한 개념 및 체계화가 이루어지지 않고 있으며 대부분 현장소장의 경험에 의존하고 있기 때문에 체계적인 공사수행에 차질을 빚는 등 많은 문제점이 나타나고 있다. 이에 본 연구를 통해 전체 Pre-con 단계 중 종합건설회사내에서 시공계획서작성이전 Pre-con 단계의 업무흐름을 분석하고 업무부서간의 도식화된 업무체계를 제시하고자 한다. 이를 통해 불필요한 업무론 배제하고 더 나아가 향상된 업무 흐름을 통해 체계적인 공사계획을 수립하여 본 공사에서의 효율성 향상을 기대할 수 있을 것이다.

The aim of this study was to assess the effect of pre-aeration on sludge solubilization and the behaviors of nitrogen, dissolved sulfide, sulfate, and siloxane. The results of this study showed that soluble chemical oxygen demand in sewage sludge could be increased through pre-aeration. The pre-aeration process resulted in a higher methane yield compared to the anaerobic condition (blank). The pre-aeration of sewage sludge, therefore, was shown to be an effective method for enhancing the digestibility of the sewage sludge. In addition, this result confirms that the pre-aeration of sewage sludge prior to its anaerobic digestion accelerates the growth of methanogenic bacteria. Removal rates for $NH_3$-N and T-N increased simultaneously during pre-aeration, indicating simultaneous nitrification and denitrification. The siloxane concentration in sewage sludge decreased by 40% after 96 hr of pre-aeration; in contrast, the sulfide concentration in sewage sludge did not change. Therefore, pre-aeration can be employed as an efficient treatment option to achieve higher methane yield and lower siloxane concentration in sewage sludge. In addition, reduction of nitrogen loading by pre-aeration can reduce operating costs to achieve better effluent water quality in wastewater treatment plant and benefit the anaerobic process by minimizing the toxic effect of ammonia.

The study aims to find out and examine the variables that make a difference between pre-service teachers' child care efficacy (CCE) and general self-efficacy (GSE). The subjects were 232 pre-service child care teachers going to an educational institution and a college. The results are as follows. First, the variables of "age", "teacher training facilities", "field experience in child care centers", and "experience of child care" and "paraprofessional teachers" are important variables in pre-service teachers' CCE. Second, the variables of "age", "level of education", "teacher training facilities", "field experience in child care center", and "experience of child care or paraprofessional teachers" significantly affect the pre-service teachers' GSE. Third, the "age" variable is essential in explaining pre-service teachers' GSE. The Pre-service teachers' GSE is significantly related to the pre-service teachers' CCE.

The study aims to discover the scope of pre-service special education teachers' knowledge and perceptions of using computer technology in teaching students with disabilities from a pre-service teacher (PST) perspective in light of the gender and sub-major variables. The sample consisted of 84 MEd students/pre-service teachers at the Department of Special Education, Faculty of Education, Umm Al-Qura University. The descriptive analytical approach is used due to its relevance to the study. A survey consisting of the participant's basic information section and 12 statements was sent to a set of pre-service teachers. Findings showed that pre-service special education teachers had an overall high knowledge of using computer technology (M=3.93). Findings also indicated that there were no gender- or major-related statistically significant differences (α = 0.05), in pre-service special education students' knowledge and perceptions of using computer technology.

The purpose of this study is to find student factors associated with the students' evaluation of university teaching, and to provide a meaningful reference to policy-making of teaching evaluation. Based on the surveyed questionnaires from 232 students who participated in e-learning course. in combination with applying descriptive statistics, this study analyzes (1) the influences of students' pre-motivation level of student based-on ARCS theory on class satisfaction, (2) the influences of students' grade, attendance, and class involvement on class satisfaction, and (3) the influences of e-learning experience on students' pre-motivation level and class satisfaction. Result of this study shows that: (1) students' pre-motivation level including Attention(A), Relevance(R), Confidence(C), and Satisfaction(S) is positively correlated to students' evaluation for teaching, (2) students' grade, attendance. and class involvement are positively correlated to students' evaluation for teaching, and (3) students' e-learning experience is not related with students' pre-motivation level, whereas it is related with class satisfaction.
